T 0 all whom it may concern:

Be it known that LVFREDERIC E. WoRDnN, a citizen of the United States,residing at" Hudson, county of Lenawee, State of Michigan, have inventeda certain new and useful Improvement in Water-Change Valves, and

declare the following to be a full, clear, and exact description of thesame, such as will enable others skilled in the art to which it pertainsto make and use the same, reference being had to the accompanyingdrawings, which form a part of this specification.

This invention relates to water change valves for well pumps and thelike, and has for its object an improved construction and arrangement ofparts. The distribution valve and its packing nut may be located in rthe pump system at a point below frost level and yet may be easilyremoved for repair without requiring the disconnection of one Fig. 2 isa partly sectional view of the va-.

rious chambers of the valve shell and of the connections to thevariouspipes, the valve being in position to direct the flow of water into theupper or spout pipe.

Fig. 3 is a view similar toFig. 2, showing the valve in a differentseating position, so as to direct theflow into the underground ditch orwatering trough pipe.

Fig. 4 is a sectional plan view taken along the line w-m of Fig. 2. a

A indicates a well pump, whose supply branch B extends down into a wellor other source of supply, the piston C being adapted to reciprocate upand down in the usual way as the handle D is actuated. The upper end ofthe pipe B is connected with the chamber F of the casing E, and in theside wall of the chamber E is locateda passage G leading to the chamberH, which in turn is connected by a passage J with a valve chamber K, oneend of which opens into the upper end of the ditch or watering troughpipe L, andin the other end of which is located a passage P which leadsinto the.

pocket or chamber Q, with which the lower end of the s out pipe R isconnected. The opening to t e ditch pipe L is protected by a 1wArER-cHAnGnvALvnj Specification of LettersPatent. Patefltied J 111163,

coupling M'having a valve seat N, against which the valve 0 seats whenit is desired to direct the flow of water into the spout pipe R. Axiallyin line with this seat N is the removable valve shell S, against whoseend T the valve 0 seats when it is desired to direct the flow of waterinto the ditch or watering trough pipe L. The screw threaded lower end Uof this valve'shell engages a complementarily threaded portion of theinner surface of the chamber K, while the upper portion, which engagesoutside of the casing E, is threaded to receive a removable packing nutV, through which the stem W of the valve 0 passes, its upper endreaching above the ground to a convenient position for manipulation,adjacent the pump han dle. An aperture X in the side of the shell Saffords communication between the chamber K and the pocket Q, leading tothe spout pipe R.

From the foregoing it will be evident that by raising or lowering of thestem W the valve T is caused to seat' against one or the other of theseats N and T, thereby directing the flow of water into the spout pipe Ror ditch pipe L as desired. At the same time the entire valve shell S,and the valve 0 with its stem W can be easily removed from the chamber Kby unscrewing, without in any way disturbing any of the other connections leading to or from any part of the casing E. At the same time,the packing nut V, constituting as it does a portion of the removablevalve shell S is not required to be above the ground surface andtherefore exposed to freezing, but is located in the ground below thefrost line.

For the holding'of the stem W in raised position, I have shown its upperend screw threaded as at Y for engagement through a complemeutarilythreaded bracket or projection Z on the frame of the pump. It isobvious, however, that other equivalent coned with one of the endchambers, discharge pipes connected with each of two others of saidchambers, an axially disposed valve seat in ene of said chambers, ashell memher i'elnovahly located partly Within and seat, a piston memberdisposed between said valve seats 1n posltlon to seat agalnst eltherandto thereby shut off the flow to one or the other of the dischargepipe apertures, an

actuating stem for said-plston memberex- 10 tending through saidremovable shell memher, and a packing nut through which said stemextends to an outside point, located on the outer end of the valveshell.

In testimony whereof, I" sign this specification inthe presence of tWoWitnesses.
